Disable Office365 Legacy Protocol Access - Remove Excluded Users

Monday 11th November 2019 08:00 AM

Purpose: In an effort to increase the security of our Office 365 tenant and our on-prem environment, we are going to remove the 555 users in the current conditional access policy for legacy protocols per CR-86. This will disable all legacy protocols on Office365 mailboxes excluding Skype for Business Exchange EWS dependencies.

Impact: MEDIUM

Affected: Office365 users leveraging SMTP, IMAP, and POP3 legacy protocols
